A better way?

I’m making a bunny buddy blanket free pattern from Lionbrand. I have made it before, but was just wondering IS THERE A BETTER WAY TO KNIT THE HEAD??? The pattern says to p1 slip 1 but I noticed that the holes it causes are too big to keep the stuffing inside. Any suggestions? Also, There are 2 knit patterns for this. On one, the ears are attached(the other you have to sew them on)- so on the one with the attached ears, where do I stuff the head from- the open ear?? Please help Thanks!

You could use a smaller needle than suggested by the yarn to make the stitch tighter. That is usually recommended for anything with stuffing. I tend to go d own a couple needle sizes at least.

I haven’t made the pattern so I’ll look at it as soon as I have some time.
